22: * This file implements AIM's clientLogin procedure for authenticating
23: * users. This replaces the older MD5-based and XOR-based
24: * authentication methods that use SNAC family 0x0017.
25: *
26: * This doesn't use SNACs or FLAPs at all. It makes http and https
27: * POSTs to AOL to validate the user based on the password they
28: * provided to us. Upon successful authentication we request a
29: * connection to the BOS server by calling startOSCARsession. The
30: * AOL server gives us the hostname and port number to use, as well
31: * as the cookie to use to authenticate to the BOS server. And then
32: * everything else is the same as with BUCP.
33: *
34: * For details, see:
35: * http://dev.aol.com/aim/oscar/#AUTH
